Experimental Synthetic Aperture Radar with Dynamic Metasurfaces
, 2017 We investigate the use of a dynamic metasurface as the transmitting antenna for a synthetic aperture radar (SAR) imaging system. The dynamic metasurface consists of a one-dimensional microstrip waveguide with complementary electric resonator (cELC ...

Near‐field scattering centre modelling for complex targets
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2657-2666, December 2024.In this paper, the authors presented the near‐field scattering centre model with the dependence description of radar distance. The model can be used to quickly calculate the near‐field scattering field and radar image features of complex targets. Abstract The parametric scattering centre (SC) model of the target has been widely used in the rapid ...

Target Oriented High Resolution SAR Image Formation via Semantic Information Guided Regularizations
, 2017 Sparsity-regularized synthetic aperture radar (SAR) imaging framework has shown its remarkable performance to generate a feature enhanced high resolution image, in which a sparsity-inducing regularizer is involved by exploiting the sparsity priors of ...

A novel multi‐target TBD scheme for GNSS‐based passive bistatic radar
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2497-2512, December 2024.The paper presents a novel approach to enhance low‐altitude surveillance in urban and suburban areas using GNSS‐based passive bistatic radar systems. Despite challenges such as weak signal power budget and complex multi‐target tracking, the proposed method introduces a track‐before‐detect (TBD) strategy with a DCCF‐based cluster centroid extraction ...

ISAR Imaging of Ship Targets Based on an Integrated Cubic Phase Bilinear Autocorrelation Function
Sensors, 2017 For inverse synthetic aperture radar (ISAR) imaging of a ship target moving with ocean waves, the image constructed with the standard range-Doppler (RD) technique is blurred and the range-instantaneous-Doppler (RID) technique has to be used to improve ...

2-D Coherence Factor for Sidelobe and Ghost Suppressions in Radar Imaging [PDF]
, 1956 The coherence factor (CF) is defined as the ratio of coherent power to incoherent power received by the radar aperture. The incoherent power is computed by the multi-antenna receiver based on only the spatial variable.
